Output Current Limiting
When the output is overloaded above the
maximum output current rating, the voltage will
start to reduce to maintain the output power to a
safe level. In a condition of high overload or
short-circuit where the output voltage is pulled
below approximately 30% of Vo.Nom, the unit will
enter a ‘Hiccup’ mode of operation. Under this
condition the unit will attempt to restart,
approximately every 100ms until the overload has
cleared.
Parallel Operation
Paralleling of two converters is possible by direct
connection of the output voltage terminal pins.
The load regulation characteristic is designed to
facilitate current sharing (typically ± 20%).
Series Operation
The outputs of two units may be connected in series to
achieve a higher system voltage.
Safety Considerations
In order for the output of the converter to be
considered as SELV (Safety Extra Low Voltage)
or TNV-1, according to EN60950 / UL1950 /
CSA60950-00, one of the following requirements
must be met in the system design:
The converter has no internal fuse. An
external fuse must be provided to protect the
system from catastrophic failure. The
recommended fuse values are shown below:
Input Voltage Range
36-75V
18-36V
9-36V
18-75V
Recommended Fuse
F0.315A
F0.5A
F1.0A
F0.5A
The user can select a lower rating fuse based
upon the inrush transient and the maximum
input current of the converter, which occurs at
the minimum input voltage. Both input traces
and the chassis ground trace (if applicable)
must be capable of conducting a current of 1.5
times the value of the fuse without opening.
The fuse must not be placed in the grounded
input line, if any.
These converters feature 1500 Volt DC isolation
from input to output. The input to output
resistance is greater than 10MOhm. These
converters are provided with Operational
Insulation between input and output circuits
according to EN60950 / UL1950 / CSA60950-00.
Nevertheless, if the system using the converter
needs to receive safety agency approval, certain
rules must be followed in the design of the
system. In particular, all of the creepage and
clearance requirements of the end-use safety
requirements must be observed.
These
documents include UL60950, CSA60950-00 and
EN60950, although specific applications may
have additional requirements.
If the voltage source feeding the module is
SELV, the output of the converter is
considered SELV and may be grounded or
ungrounded.
The circuitry of the converter may generate
transients, which exceed the input voltage.
Even if the input voltage is SELV (<60V) the
components on the primary side of the
converter may have to be considered as
hazardous. A safety interlock may be needed
to prevent the user from accessing the
converter while operational.
